BREAD-MIXER.

Specification of Letters Patent.

Patented J une 7, 1.910.

Application filed May 5, 1909. Serial No. 494,131.

To all whom it may concern:

Be it known that I, Gosfrn FRinDMAN, of Jamestown, in the county ofChautauqua and State of New York, have invented a new and usefulImprovement in Bread- Mixers. which improvement is fully set forth inthe following specification and shown in the accompanying drawings.

This invention relates to certain new and useful improvements in breadmixers and it has for its objects among others to provide a simplifiedand improved construction of mixer involving a peculiar form of flasheror s't-irrer, means for holding the saine against displacement and alsosimple yet efficient means for holding the crank to the shaft of theydasher.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be particularly pointed out b-y theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the numerals of reference marked thereon, form a part ofthis specification, andl in which- Figure 1 is a substantially centralvertical section through a bread mixer constructed in accordance with mypresent invention. Fig. 2 is a top plan thereof. Fig. 3 is a detail,partly in elevation and partly in section, the same being taken as onthe line 3MB of Fig. 1. Fig. Ll is a perspective view of the dasherremoved. Fig. 5 is an enlarged detail, partly in elevation and partly insection, with portions broken away, showing the cooperating portion ofthe dasher shaft and crank.

Like numerals of reference indicate like parts throughout the severalviews.

Referring to the drawings, 1 designates the vessel or receptacle of anysuitable material, shape and capacity, prefer: bly, however, of the formseen in Figs. 1, 2 and 3. The bottom of the vessel or receptacle istapered from opposite sides, as seen at 2 2, the taper being so disposedthat the depression 3 formed thereby shall be disposed longitudinallysubstantially in a vertical plane axially with the shaft of the dasher,as will be readily understood upon reference to Figs. 2 and 3, wherebythe dasher in its movements follows the path in quite close proximity tothe bottom of the vessel formed by the two tapered sides and the bottomproper of the vessel therebetween so that the entire contents may beacted upon by the dasher.

The vessel or receptacle is provided at a suitable point, in thisinstance, at about oncthird of the height from the bottom, with a closedbearing l upon one side and an open bearing 5 at the diametricallyopposite side, as seen clearly in Figs. 1 and 2. The open beariing` isreil'ilorced or strengthened exteriorly, as at (5, so as to give therequisite rigidity.

The dasher or stirrer is mounted in these bearings. This dasher isformed of a single piece of material, preferably round wire, of therequisite size and. strength, one end thereof forming the pintle 7 whichis rcceived within the bearing Ll and the other end forming pintle 8received in the bearing 5 and having a flattened side, as shown at 9 inFigs. 4 and 5. Between its ends, the dasher is provided with the doublereverse curved portions 10 and 11 in the forin ot' complete closedloops, as shown best in Figs. 1 and 4, the same being formed by coils ofthe wire or material of which the saine is composed, the curved portionsbeing in substantially the same plane, the two terminal bearing portionsextending in substantially the saine plane, as seen best in Figs. 1, 2and 4.

12 is the crank having a suitable handle 13 at one end and at the otherhaving a hollow right angled portion 14 within which the end of thepintle 8 of the dasher is received. This hollow portion has extendingtherethrough within the same a tangent pin 15 for coaction with theflattened side of the pintle 8, as seen clearly in Fig. 5. The extremeinner end of the hollow portion of the crank forms a hollow bearing 16received within the bearing 5, and adjacent thereto is the annulartia-nge or collar 17 which is designed to bear against the outer vfaceof the enlargement G of said bearing 5, as will be evident from Fig. 1.Vhen the 'crank is put in place on the mixer, it occupies the plane ofthe double reverse curves or loops of the mixer, the whole being in thesame plane, as will be evident from Figs. 1 and 2. rlhe crank is engagedby simply placing it in its proper position with relation to the end ofthe dasher stem or shaft and then inserting the latter into the hollowmember of the crank, when the pin rides on the flattened face of the endof the stem and rotation of the crank serves to revolve the dasher onits bearings.

In order to hold the crank in place, I provide a slide 18 having aVsuitable handle portion 19, said slide being mounted for movement andguided in a` suitable guide 2O cured to the outer wall of the vessel 1and havingl its lower end bifurcated, as seen at 21, to receive thladjacent part of' the crank, the slide being slightly ofl'set near itslower end, as at 22, so that the branches ofl the slide will comeoutside of' the flange or collar 17 of the crank.

In assen'ibling the parts. the flattened end of the dasher is insertedfrom tho inside of the vessel and projected outwznfdly through thebearing 5 and the other end 7 then engaged in the bearing 4l. The crankis then slipped on to the j )rojectng end of the pintle 8 of the stem ofthe dasher and the slide 1S pressed down until its bifurcated ondengages over the adjacent portion of the hollow member lll; of thecrank, as seen in Figs. l and 3, engaging the outer face of the flangeor collar 1T on said hollow portion and pressing the same against theouter face of the enlargement G of the bearing 5, thus locking the partstogether and preventing displacement of the crank or dasher.

The operation will be apparent from the foregoing description, whentaken in connection with the annexed drawings, and a detaileddescription thereof not deemed necessary.

What is claimed as new :M

l. In a bread. mixer, a dasher formed of one continuous piece ofmaterial having pintles at the ends and intermediate double reversecomplete closed loops, one of' said pintles having' a flattened side,combined with a cranl; having a hollow portion to receive the pintle anda tangent pin to engage said flattened side.

2. In a bread mixer, the combination wit-h a vessel having bearings, ofa dasher having` its ends received in said bearings, one end projectingthrough its bearing and having al flattened portion, a crank having ahollow portion and tangent pin to receive said projecting end and engageits flattened portion, and an exterior collar, and a slide mounted onthe exterior of the vessel and having bifurcated end to receive saidhollow portion and engage said flange.

3. In a bread mixer, the combination of a vessel and a dasherhavingbearings therein with one end projected and flattened, a crank having' atubular portion receiving said projecting end, a tangent pin extendingtransversely through said tubular portion to coact. with said flattenedportion, said tubular portion having a hollow bearing at its inner endand an annular flange adjacent thereto.

il. In a bread mixer, the combination with a vessel and a dasher havingbearings therein with one end projected and flattened, a crank having atubular portion receiving said projecting end and an annular flangebearing against the outer face of the adjacent bearing and a. hollowbearing received within said bearing, a tangent pin passed through saidtubular portion between the inner wall thereof and the flattened portionof the extended bearing of the dasher, and a verticallj movable slidehaving an offset portion near its lower end and branches engaging thetubular portion of the crank and bearing against its annular flange.

In witness whereof, I have hereunto set my hand this 28th day of April,1909, in the presence of two subscribing witnesses.
